This driveway had a golf cart's batteries rinsed off and left dark stains running down the driveway - we've cleaned it fairly well by pouring "The Works" household cleaner onto it - but some residual remains. (see photo) We could keep going and even it out, however it appears it will not come off completely. [I](Our next thought/attempt might be a diluted muriatic acid wash and power wash.)[/I] The landlord hasn't seen our first pass but originally said he wants it "back to the way it was" - so we likely need to further clean or [B]discolor it[/B] to match the old driveway. It's NOT very much area - the whole driveway is only about 12 yards long and 4 yards wide at most. Any suggestions? We only need to do a [B]simple, temporary cover up[/B] to it - not a major improvement - the driveway was in poor shape to begin with but we fear they will try to keep our $1500 deposit and say it needs a whole new driveway. How about a bag of cement, diluted to almost water consistency spread around on top? Or something else? It there a paint that looks just like concrete we could spray a light coat on top?

We are looking into building a 3 season porch here in S/E Wisconsin, and I had a couple questions. The porch will butt up against 2 right angle walls, so there would be 2 frost walls. Floor height is about 16" above grade. Porch will be about 13' X 19'. We are getting mixed opinions on whether to use a frost wall or concrete pier footings. So far I've gotten the following recommendations: 1) Build a frost wall and a concrete slab floor. Insulate walls and slab with 2" rigid foam insulation. 2) Build a frost wall, top with 2X6 treated sill plate, with joists on top of sill plate. 3) Use concrete pier footings, with beams and joists like a standard deck. Although it will be more expensive, I like the idea of the frost wall because the sides and bottom will be all sealed up, eliminating critters getting under the porch, and bugs. What do you guys recommend? Thanks.
